Abstract
A bolsterless air spring wide-gauge coach bogie comprises a frame, a journal spring, a height valve, a transverse shock absorber, a traction support, a differential pressure valve, a transverse baffle, wheels and an axle, wherein an axle swiveling jib is arranged between the side beam of the frame and the axle, while a simplex pull rod is arranged between the beam of the frame and the traction support, the side beam is provided with an air spring above, a brake disk is installed on the axle body of the axle, the beam is provided with a disk brake hanging base provided with a brake cylinder and a brake clamp. The swiveling jib type positioning is used to replace the pedestal frame type positioning in the utility model, thereby improving the critical speed and operation stability of the bogie, while the central traction uses simplex pull rod to tract, so space is saved, good manufacturability and simple maintenance can be realized, and the basic brake is disk-type brake, which has the advantages of simple structure and high reliability.
Description
Technical field:
The utility model relates to railway passenger car bogie, especially relates to a kind of broad gauge swing-bolster-free air spring passenger car bogie.
Background technology:
Bogie truck is a passenger train traveling portion, and broad gauge swing-bolster-free air spring bogie truck is a kind of bogie truck of special purpose, is applicable to broad guage line.Bogie truck is made up of framework, axle-box positioning device, secondary suspension device and foundation brake rigging.Bogie truck is one of critical component of vehicle, and the performance of bogie truck plays important effect to vehicle.Whether the stationarity of vehicle operating, safety meet standard, depend primarily on the design of bogie truck.China does not also have swing-bolster-free air spring broad-gauge passenger bogie truck at present, and external broad gauge bogie truck ubiquity the shortcoming that running velocity is low, the stationarity safety is relatively poor, can't satisfy the operating needs of 140km/h.
Summary of the invention:
Technical problem to be solved in the utility model provides all satisfactory 140km/h swing-bolster-free air spring of a kind of stationarity, safety broad-gauge passenger bogie truck, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise framework, journal box spring, levelling valve, lateral damper, traction bearing, valve for pressure difference, horizontal retaining, wheel, axletree, the axle box pivoted arm is set between truck side sill and axletree, be provided with simplex pull rod between truck transom and the traction bearing, the truck side sill top is provided with air bellow, on the axle body of axletree brake disc is housed, truck transom is provided with the disc braking flap seat, and brake cylinder and braking clamp are installed on the disc braking flap seat.
The utility model axle box location changes the pivoted arm location into by the drawing strickle guide formula, improved the critical speed and the running stability of bogie truck, the simplex pull rod traction is adopted in central authorities' traction, has saved space, good manufacturability, easy to maintenance, foundation brake adopts disc braking, and is simple in structure, safety performance is reliable.
